www.DataSheet4U.com R2A20111SP/DD Power Factor Correction Controller IC REJ03F0231-0100 Rev.1.00 Mar 28, 2007 Description The R2A20111 is a power-factor correction (PFC) controller IC. This IC adopts continuous conduction mode as PFC operation. Various functions such as constant power limit, overvoltage detection, overcurrent detection, soft start, feedback-loop disconnection detection, and holding function of PFC operation through momentary outage (PFC hold function) are incorporated in a single chip. These functions reduce external circuitry. The constant power limit function allows to eliminate a significant amount of coil noise which is generated due to overcurrent detection operation in case of conventional overload.
